Streszczenie: Artykuł zawiera wybrane rezultaty prac symulacyjnych, obejmujących możliwość instalacji małogabarytowych opraw iluminacyjnych ze źródłami LED w bliskim otoczeniu oświetlanego obiektu. Jako przykład prac szczegółowych został wybrany Pałac Lubomirskich w Przemyślu. Kolejno przedstawiono wyniki prac etapu modelowania geometrycznego obiektu, doboru modeli opraw iluminacyjnych oraz ich rozmieszczenia i nacelowania. Finalnie po zakończeniu obliczeń komputerowych przedstawiono wybrane wyniki wizualizacyjne oraz rozkładu luminancji.
Abstract: Application of solid-state light sources in luminaires creates a new quality in illumination design works. In confrontation to commonly used but relatively unattractive flood method, use of small size luminaires allows to present illuminated architectural object in more attractive way in evening and night time. In this case it is possible to apply the principles of illumination described in the literature, especially the principle of height amplification and the principle of depth amplification. The conceptual work of illumination with the use of a large number of small-size luminaires does not require the use of supporting graphical tools, but the specification of actual lighting equipment using only polygonal samples in this case is not possible. The paper presents selected issues of the key stages of the completed work. Using specialized computer software, a geometric model of the architectural object has been developed, façade materials have been parameterized, models of small-size illuminating equipment have been selected and, finally, calculations of luminance distribution on illuminated surfaces have been carried out. As a result of computer work, luminance distributions and photorealistic visualizations of illuminations from defined main directions of observation were obtained. The Lubomirski Palace in Przemyśl is an example of architectural object indicated for detailed works.
